Hi,

solved using "ms-python.python@prerelease" instead of current stable version.

Would be nice to allow specify the prerelease tag for recommendations in extensions.json

I also got this error discovering pytests tests and using the python extension pre-release version fixed it.

I wonder if there's a bug with the latest release version?

@chemelli74 thanks for reporting this and sorry for the late response. Wondering if you still seeing the issue with the stable version of the extension?

Hello! Can you provide your versions for the python extension?

[chemelli74]

Working version I'm using is

Ok so the issue is that you are seeing is because of the rewrite we had under an experiment which we just turned to be the default behavior (which you are now seeing in the pre-release version). The pre-release now got you on the rewrite which is why it was it fixed.

@a-lapedriza if you are still seeing an issue, please open a new issue in the vscode-python repo and we can look through your issue specifically. Thanks!

This is not solved using latest release:

[eleanorjboyd]

Are you able to try it on the pre-release? It is not out on the latest stable version: version 2024.22.2

Sorry, I don't get the question.
I already reported that using pre-release it works fine.
